south today.

PREV DISCUSSION... /issued 405 AM CST Sat Dec 7 2019/

DISCUSSION...
South winds will return by this afternoon as a lee low deepens
over SE CO. A LLJ will develop overnight and with it will come
warmer temps and low level moisture. Stratus should spread
northward along and east of I-35 by early Sun morning although it
should be brief as 850 flow veers ahead of an approaching front.
Above avg temps in the 60s and 70s will be possible within this
downslope flow Sun afternoon.

Cirrus will begin to increase late Sun through Mon as a long fetch
of upper moisture extends from the northern Baja into the midwest,
with an elongated mid to upper trough axis swinging through the
southern Rockies. Enough moisture and lift will be present near
the Red River by late Mon behind the cold front, although it
appears winter precip chances will remain low based on the timing
of the coldest air. The moisture and lift quickly shift
southeastward after 12Z Tue and clearing skies should result in a
fairly cold morning from I-40 northward. Some locations will drop
into the upper teens across NW OK with a ~1025 mb high parking
over OK and west OK.

Temps should remain near or just below average through the rest of
the week. There is slightly better agreement in the extended
forecast, with a pair of shortwave troughs now advertised Thu
somewhere over the plains and lee of the Rockies. Right now, it
appears too dry in the mid levels for any precip late this week
with the southern wave although cirrus will be streaming overhead
on and off.
